Hey Guys,
 

I'm facing a challenging situation with my home network and urgently need some advice. I have an Asus RT-AX58U router and recently added a TP-LINK RE700X (Ethernet Port) range extender to improve wifi coverage in my house.
 

Here's the core of my issue: I'm trying to set time-based internet restrictions for my son's devices (a phone - WIFI EXT and a desktop-Ethernet), which connect to the internet through this extender. The aim is to manage his internet usage due to specific personal needs. While the router recognizes the extender and shows the connected devices with their MAC addresses, I can't get the time-based restrictions to work for these devices. His phone is connected via WIFI (separate/EXT SSID) and his desktop is connected to the extender via an Ethernet cable.
 

The router's firmware is up to date, and I've gone through the settings multiple times to ensure everything is configured correctly (although I'm not an expert). But no matter what I do, the devices connected through the extender seem to bypass these restrictions.
 

This situation is causing a lot of stress, as unrestricted internet access is not suitable for my son's condition. I'm looking for any advice, workarounds, or settings that I might have missed to resolve this issue.
 

Has anyone else experienced something similar or knows how to make the Asus router's time restrictions work with a TP-LINK extender? Any insights or guidance would be greatly appreciated!
 

Thank you in advance for your help!
